Abstract

(57) [Abstract] [Purpose] To obtain an orthodox mirror that allows you to see the true image (orthogonal image) of the scene including yourself as seen from the other person. [Structure] 1. Two plane mirrors are fixed in a box by connecting and arranging them so that their reflecting surfaces are on the inside and their angles are 90 °. 2. A prism with an isosceles right triangle cross section is fixed in the box. 3. Attach two flat mirrors to the hinged frame that opens and closes,
A stopper is provided on the mirror frame to fix the flat mirror at a position where the flat mirror faces each other at a right angle.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a normal image mirror that uses two plane mirrors or right-angle prisms and can see by itself the same normal image as seen from the other person, as in a photographic screen, instead of a left-right inverted image. is there.

[0002]

[Prior art]

 It is well known that in a conventional plane mirror, a person facing the plane mirror sees a virtual image of an object, including the self, which is mirrored to the left and right, and is the same as that seen by a person facing the plane, such as a photographic screen. I couldn't see the statue myself.

[0003]

[Problems to be solved by the device]

 In the conventional technology, there was a problem that the mirror could not see the normal image of the object including the self (the image in which the left and right sides were not inverted) by itself, and it was not possible to see the correct image of the self seen from other people. .

It is an object of the present invention to solve the above problems and provide a normal image mirror that allows one to see by himself the true appearance (virtual image) of a scene including himself viewed from another person.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, in the normal image mirror of the invention as claimed in claim 1, two plane mirrors are connected in such a manner that their reflecting surfaces are inside and face each other at an angle of 90 °, and are fixed in a box body. Is.

In the normal image mirror of the second aspect of the invention, a prism having an isosceles right triangle cross section is fixed in the box body.

In the normal image mirror according to the third aspect of the present invention, the two plane mirrors are attached to the two lens frames which are connected so as to be opened and closed by the hinge-shaped projections so that the reflection surface is on the inside. With the stoppers on the protrusions engaged when the flat mirror is opened, the flat mirrors hold the reflective surfaces at an angle of 90 ° to each other, and when the flat mirror is closed, the reflective mirrors can be folded and stored, making the structure convenient for carrying. Is.

[0008]

[Action]

 As shown in FIG. 9, the present invention applies the principle of generating a virtual image by two plane mirrors facing each other at an angle of 90 °, and a light beam emitted from an object (M) has two plane mirrors (1 A). , (1B) is reflected twice and the virtual image (m) appears, but this virtual image is the same as the one seen from the mirror side of the object.

The normal image mirror of claim 3 is designed for portable use and has a notebook-like appearance, and when two closed lens frames are opened, the lens frames are placed above and below. When the processed projections form a hinge and rotate and the plane mirrors fixed to the lens frame become 90 ° to each other, the projections and recesses of the stoppers on the projections engage and stop.

[0010]

【Example】

 In the embodiment of the invention of claim 1, as shown in FIG. 1 and FIG. 2, two plane mirrors 1A and 1B are connected so that their reflecting surfaces are inside, and they are connected to each other at one ridge side and face each other at 90 °. It is mounted and fixed in the box body 3 whose front surface is opened. At this time, if the mirror plate is a glass plate whose surface has been subjected to a mirror surface treatment such as mercury vapor deposition, or a metal plate such as a mirror-finished aluminum plate is used, the connecting portions of the flat mirrors 1A and 1B are not conspicuous. A clear normal image can be obtained. Further, if the plane mirrors 1A and 1B are made into an integral structure, the effect is further enhanced.

In an embodiment of the invention of claim 2, as shown in FIGS. 3 and 4, two surfaces sandwiching a right angle of a prism 2 of a triangular prism having a right-angled isosceles triangular cross section are subjected to a mirror surface treatment, It is attached and fixed in the box body 3 that has been opened.

In the embodiment of the invention of claim 3, as shown in FIG. 5, FIG. 6, FIG. 7, and FIG. 8, two plane mirrors 1A and 1B are bonded and housed by using a material such as plastic. Two lens frames 4A and 4B are openably and closably coupled by hinge-shaped protrusions 4a and 4b formed on the upper and lower ends thereof, and the stoppers on the protrusions 4a and 4b face each other in a convex shape and a concave shape. By providing the portions 4c and 4d, the plane mirrors 1A and 1B are stopped and fixed at an angle of 90 °.

[0013]

[Effect of the invention]

 Since the present invention is configured as described above, it is possible to solve the problem to be solved by the above-mentioned invention and to see by oneself the true figure (orthogonal image) of the scene including self as seen from another person, Furthermore, the device of the third aspect of the invention has the effect that the device can be easily folded and carried.
